Answer:
In a closed system where volume is held constant, there is a direct relationship between Pressure and Temperature. In a direct relationship, one variable follows the same change when it comes to increasing and decreasing. For example, when the pressure increases then the temperature also increases. When the pressure decreases, then the temperature decreases.
EXAMPLE:
spray can. The volume of the can is constant. When contents are removed from the can, then the mass of the contents will be reduced in the can. Because there is less mass in the can with a constant volume, the pressure will decrease. This pressure decrease in the can results in a temperature decrease. The contents coming out of the can also cool in temperature but for another reason. Outside of the can the volume is not held constant. Thus the contents are free to expand when they move from the high pressure in the can to the low pressure outside of the can. Expansional cooling causes the contents coming out of the can to cool. This effect can be noticed in spray-on deodorants.
